You are missing the point. It will surely look good on all cards, but you may get better performance with a radeon. At least at the start, depends on how much they have optimized it before the release.
Anyway, that's really off topic.
I'm running on medium and no shadows, 1024x768, no AA, no AF, low sound quality (supposedly it runs better). Then again, I just started playing it
Can't wait for the patch on friday, that's gonna fix alot of problems for me and other ATI users
